Generalize AutofillTable::RemoveAllAutofillProfiles()

Currently this function only works for kAccount profiles (and is only
used for such). Due to the new shared table layout, it can easily be
adapted to work for kLocalOrSyncable profiles too.

With that, AutofillTable::ClearAutofillProfiles() (which currently only
deletes local profiles) can be removed and replaced with
AutofillTable::RemoveAllAutofillProfiles(kLocalOrSyncable).
